Solution
Electrical current is a measure of the amount of electrical charge transferred per unit time. It represents the flow of electrons through a conductive material.
Current is a scalar quantity (though in circuit analysis, the direction of current is relevant).
The SI unit of electrical current is the ampere, defined as 1 coulomb/second.
An electric circuit can be defined as a closed path through which electric current can flow. Various components such as battery, resistor, wire, key, bulb etc can be connected in different ways to construct an electric circuit.
